TPS78618KTTRG3 Description

Short technical summary and product information.

The Texas Instruments TPS78618KTTRG3 is a 1.5A low-dropout (LDO) linear voltage regulator designed for applications requiring high power supply rejection ratio (PSRR) and ultralow noise. This device provides a fixed 1.8V output voltage and is stable with a 1µF ceramic capacitor.

 

Key electrical characteristics include a maximum input voltage of 5.5V, a minimum input voltage of 2.7V, and a typical dropout voltage of 390mV at full load. The regulator features excellent load and line transient responses, fast start-up time of 50µs, and a quiescent current of 0.26mA typical. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS78618KTTRG3 is available in a TO-263-5 (DDPAK) surface-mount package. Its noise performance of 48µVrms and high PSRR (59dB at 100Hz, 32dB at 100kHz) make it ideal for sensitive analog circuits, RF applications, and audio systems.

 

This regulator is designed for applications such as RF (VCOs, Receivers, ADCs), Bluetooth, Wireless LAN, cellular telephones, and handheld organizers.
